Q1 How to reduce the eddy current losses?? The eddy current losses can be reduced by laminating the core and insulating it from each other with the help of either a paper or a varnish. Q2 What are the advantages…
Difference between the alternator and generator is given here, which explains how they are different from each other with respect to structure, output, efficiency, etc. These alternator and generator differences can help to clear any doubt regarding this topic. Here,…
The capacity to do work is called Energy. This energy can be stored in different forms. Energy is one of the physical quantities as it is proportional to the mass of the object. The ability of the body to exert…
Difference between Concave and Convex Lens A convex lens or converging lens focuses the light rays to a specific point, whereas a concave lens or diverging lens diverges the light rays. A lens is a transparent material (either curved or…
Q1 Why can’t AC be stored in batteries instead of DC? It is important to understand that batteries do not store the energy directly in them. They store electrical energy in the form of chemical energy. The positive terminal of…
Electric current flows in two ways as an alternating current (AC) or direct current (DC). The main difference between AC and DC lies in the direction in which the electrons flow. In DC, the electrons flow steadily in a single…
Resistance is defined as the property of the conductor which opposes the flow of electric current. It is also defined as the ratio of the voltage applied to the electric current flowing through it. The resistance of a conductor depends…
Q1 What is slip in a motor? For an induction motor, slip is defined as the difference between the synchronous speed (Ns) of the rotating field and the rotor speed N. It is expressed as the percentage of synchronous speed…
The difference between AC and DC motors is extremely important not only from the examination point of view, but also for various projects and practical demonstrations. By knowing the AC and DC motor differences, choosing the right one for a…
Q1 What is heat? Heat is the energy that is transferred from one body to another due to differences in temperature. Q2 What is temperature? Temperature is a physical quantity that expresses the coldness and hotness of a body. Q3…
